Pivot bearing for camera crane
A mobile camera crane, which is mounted on vehicles, is to be swivel-mounted. The bearing must be able to withstand high tilting moments due to the boom. Lightweight construction and robustness against shocks and vibrators are further requirements for the bearing.
Bearing assembly with weight-reducing bore holes and a round wire without raceway.
The bore holes reduce the weight by almost 50%. The round wire cannot tilt under load and ensures full function of the bearing even if the basic construction twists.
